Abstract

A liquid crystal display device includes a liquid crystal display panel, a functional panel, a photo curable adhesive, a transparent electrode, and a light blocking line. The liquid crystal panel includes a display area to display an image and a non-display area surrounding the display area. The functional panel is attached to the liquid crystal panel, and includes a display overlapping area overlapping with the display area and a display non-overlapping area overlapping with the non-display area in a plan view. The photo curable adhesive is arranged between the panels and cured by light applied thereto. The transparent electrode is arranged in the display overlapping area and made of light transmissive conductive material. The light blocking line is arranged in the display non-overlapping area and made of light shielding metal material. The light blocking line partially has a light-transmission cutout that is configured to allow the light to pass therethrough.

Dependent claims

A display device comprising:

a display panel including a display area in which an image is displayed and a non-display area surrounding the display area;
a functional panel attached to the display panel, the functional panel including a display overlapping area overlapping with the display area in a plan view and a display non-overlapping area overlapping with the non-display area in a plan view, the display non-overlapping area including a portion in which an electrical component is to be connected;
a photo curable adhesive between the display panel and the functional panel and cured by light applied thereto, the photo curable adhesive extending over an entirety of the display area and over a majority of the non-display area excluding a portion of the non-display area overlapping the portion of the display non-overlapping area in which the electrical component is to be connected;
a transparent electrode arranged in the display overlapping area of the functional panel and made of light transmissive conductive material;
and
a light blocking line arranged in the display non-overlapping area of the functional panel and made of light shielding metal material, the light blocking line including a plurality of light transmission cutouts that allow the light to pass therethrough, wherein
the light blocking line includes:
a first portion overlapping the photo curable adhesive;
and
a second portion not overlapping the photo curable adhesive, wherein each of the first portion and the second portion includes the plurality of light transmission cutouts.
